Description

  The present invention relates to an airtight pan lid structure that is easy to operate, smooth and has a solid structure when cooking food in the kitchen. In particular, the handle of the pan lid and the movable valve that releases the airtight state of the pan are various types. The present invention relates to an airtight pan lid structure that can be applied to a pan.

  Various cooking pans such as frying pans, shallow pans, deep pans, or pans with multiple functions are usually used with a pan lid. Using a pan lid to cover the top of the pan prevents heat dissipation in the pan, improves heating efficiency, and prevents contamination of food caused by foreign objects falling into the pan. it can.

  Conventional hermetic pans can use cooking and steam expansion principles to accelerate cooking and reduce cooking time. Therefore, a rubber sealing ring is usually installed on the outer periphery of the pan lid of the airtight pan. When the open portion of the pot body is covered with the pot lid, the sealing ring produces an airtight action, whereby an airtight space is formed inside the pot lid, which is advantageous for the expansion of the steam. However, when the steam in the pot body expands, there is a difference in the pressure inside and outside the pot body, and a situation occurs where it is difficult to open the pot lid.

  In order to overcome the above-mentioned problems, an airtight pan capable of balancing the pressures of internal and external gases has been developed. As shown in FIGS. 1 and 2, the structure is provided with a through hole 82 on a pan lid 81. In addition, a movable valve 83 is installed in the through hole 82. When the user opens the pan lid 81 in a situation where there is a pressure difference between the inside and outside of the pan body 80, the user first holds the handle 85 at the apex of the pan lid 81 by hand and moves the movable valve 83 sideways. Thereby, the movable valve 83 is twisted and shifted. Thus, the through-hole 82 allows the air inside and outside the pot body 80 to conduct and releases the airtight state.

  However, in the above-described structure, a certain distance exists between the movable valve 83 and the handle 85. Therefore, the user must hold the handle 85 of the pan lid 81 with one hand and push and move the movable valve 83 with the other hand. If the handle 85 is grasped with one hand and the movable valve 83 is pushed and moved, the handle 85 must be grasped with the finger of the hand, and the finger is further extended and the movable valve 83 must be pushed and moved. . For this reason, there is a problem that the pan lid 81 is likely to fall from the hand and the operation is very inconvenient.

  Further, as shown in FIG. 2, the movable valve 83 is easily pushed and shifted, and there is a problem that the airtight state is easily released. In general, the movable valve 83 is made of a soft plastic resistant to high temperatures, and is fitted on the through hole 82 of the pan lid 81 in a movable manner. At the time of operation, since the pushing and moving angle is too large, the entire movable valve 83 falls off from the through hole 82 very easily. Furthermore, the user mistakenly thinks that the movable valve 83 is lifted up and pulled out, and the movable valve 83 may even fall out of the through hole 82.

  Furthermore, the fixing method of the handle 85 in the conventional pan lid 81 is to install a through hole 84 at the center of the pan lid 81. A screw hole 86 is provided at the bottom of the handle 85. A screw 88 installed with a spacer ring 87 is passed through the through hole 84 upward from the bottom of the pan lid 81 and screwed into the screw hole 86 of the handle 85. Thus, the spacer ring 87 is in close contact with the outer edge of the through hole 84 at the bottom of the pan lid 81.

  However, the external force when the user lifts the handle 85 acts on a single contact point between the screw 88 and the screw hole 86 located in the through hole 84. If the screw 88 is loose, the handle 85 will wobble very easily, causing inconvenience to the user or often requiring the screw to be retightened. On the other hand, if the screw 88 is too tight, the spacer ring 87 may be bent or deformed at the contact point, and if it is serious, the glass pan lid 81 may even burst.

  The main purpose of the present invention is to modularize the movable valve and handle of the hermetic pan lid, so that it can be easily and firmly coupled onto the pan lid, achieving the operation simplicity and the robustness of the coupling, The conventional pan lid movable valve is easy to drop off, or it is inconvenient because it is far from the handle, and because it is a method of screwing the screw into the handle, it is easy to loosen and wobble, or the spacer ring is easily bent and deformed, Or it is providing the airtight pan lid structure which can solve the problem that a glass pan lid may burst.

In order to achieve the above-described object, the hermetic pot lid structure according to the present invention includes a handle installed at the top of the pot lid.
On the pan lid, an opening corresponding to the handle is installed. At the end of the handle, a passage opening communicating with the opening is installed, and a connection base is provided between the opening and the passage opening. Fix and join, and install a through hole on the connection base. As a result, the through hole penetrates to the bottom of the pan lid via the opening, is exposed on the handle via the passage opening, and a movable valve capable of releasing the airtight state is movable in the through hole. Install in a shape.

When cooking of the food is completed, the handle at the top of the pan lid is grasped with one hand, and the movable valve at the top of the handle is pushed sideways with the finger of the same hand. By doing so, the movable valve is distorted and tilted, and the through-hole allows the air inside and outside the pot body to conduct, and the airtight state inside the pot body can be released. In this way, the operation process is very simple and convenient, yet smooth and can make cooking of food very easy.
The external force at the time of picking up the handle described above is dispersed on the outer peripheral wall of the connection base on average. Thereby, an external force acts on the inner wall of the open hole of the pan lid through the outer periphery of the connection base on an average. In this way, an annular contact surface is formed between the outer periphery of the connection base and the inner wall of the hole, which improves the robustness and durability of the structure, concentrates external forces at a single contact point of the pan lid, and Occurrence of curved deformation and rupture problems can be avoided.

  At the time of implementation, an external thread yama is installed on the outer wall of the connection base, and an internal thread yama that is screwed to the external thread yama is installed on the inner wall of the handle passage opening. A convex ring that adheres closely to the outer edge of the opening at the bottom of the pan lid is annularly installed on the outer wall of the connection base, and on the connection base, it is located between the handle and the pan lid and has an opening at the top of the pan lid Fit the sleeve that is in close contact with the outer edge. As a result, the handle is tightly screwed to the outer thread of the connection base through the inner thread of the passage opening, the sleeve is in close contact with the outer edge of the opening at the top of the pan lid, and the convex ring of the connection base is the bottom of the pan lid Close contact with the outer edge of the hole. In this way, the fixed joint strength between the opening and the passage opening of the connection base can be improved.

  At the time of implementation, the airtight nut of the movable valve is installed in the handle passage opening, and the inner wall of the handle passage opening limits the range in which the airtight nut is pushed and strain-shifted. As a result, the inner wall of the passage port can limit the inclination angle of the airtight nut, and can prevent the movable valve from being detached from the through hole due to excessive inclination of the airtight nut.

The present invention has the following effects.
1. The movable valve and the handle are connected to the pan lid simply and firmly by modularization, so it is convenient to hold the handle with one hand and pick up the pan lid, and use the same hand to move the movable valve. Convenient to push and move, the operation process is very simple, convenient and smooth.
2. Since the connection base can disperse the external force when picking up the handle on average, the structure's robustness and durability are improved, and the problem is that the pan lid made of glass ruptures because the screwing is too tight Can be avoided.
3. Adopting a mutual screwing system of inner thread and outer thread, and fixing the connecting base between the pan lid and the handle, the overall structure of the pan lid can be further strengthened.
4. The airtight nut of the movable valve is housed in the handle's passage opening, and the range of movement of the airtight nut can be limited by the inner wall of the passage opening, preventing the movable valve from being detached from the through hole due to excessive inclination of the airtight nut. can do.

  In the following, the technical contents, structural features, objects to be achieved and operational effects of the present invention will be described in detail with reference to examples and drawings.

  As shown in FIGS. 3 and 4, the airtight pan lid structure according to an embodiment of the present invention includes a pan lid 10 and a handle 20 installed at the center of the top of the pan lid 10. The pan lid 10 is made of a material such as metal, ceramic, or transparent tempered glass. Moreover, the pot lid 10 can cover the pot opening 91 on the top of the pot body 90. The user can pick up the handle 20. A sealing ring 30 is installed on the outer periphery of the pot lid 10. With the sealing ring 30, the pot lid 10 can be brought into close contact with the pot opening 91 of the pot body 90.

  4-6, the opening 11 penetrated up and down corresponding to the handle | steering-wheel 20 is installed in the pan lid 10 center. In addition, a passing port 21 communicating with the opening 11 is provided at the end of the handle 20 between the apex and the bottom. On the inner wall of the passage port 21, an inner screw yama 22 is installed. A connecting base 40 having a cylindrical shape is fixed and coupled between the opening 11 of the pan lid 10 and the passage opening 21 of the handle 20. Moreover, an external thread yama 41 is installed on the outer peripheral wall of the connection base 40. The connection base 40 is tightly screwed and fixed integrally when the outer screw thread 41 and the inner thread thread 22 of the passage 21 of the handle 20 are screwed together.

  At the bottom end of the outer peripheral wall of the connection base 40, a convex ring 42 that is in close contact with the outer edge of the opening 11 at the bottom of the pan lid 10 is installed in an annular shape. Moreover, the outer peripheral wall of the connection base 40 is located between the bottom of the handle 20 and the top of the pot lid 10 and close to the outer edge of the opening 11 of the top of the pot lid 10, and the bottom of the bottom of the pan lid 10 is opened. A buffer annular piece 60 located between the outer edge of the hole 11 and the convex ring 42 is fitted and installed. Moreover, an inner screw yama 51 that is screwed into the outer screw yama 41 of the connection base 40 is installed on the inner wall of the sleeve 50.

  A through hole 43 is provided between the apex and bottom of the connection base 40. The through hole 43 penetrates to the bottom of the pan lid 10 via the opening 11 and is exposed on the handle 20 via the passage port 21. Moreover, a movable valve 70 capable of releasing the airtight state is movably installed in the through hole 43. The movable valve 70 protrudes from the top of the handle 20, has an outer diameter larger than the through-hole 43, and is installed below the air-tight nut 71. The hollow vent 72 is movable up and down in the through-hole 43. 72 is provided on the outer periphery of the bottom portion, and includes a position limiting ring 73 whose outer diameter is larger than the through hole 43. Specifically, the ventilation portion 72 is installed in a soft tubular shape, and further, the side wall of the ventilation portion 72 includes a plurality of perforations 74 and communicates with the hollow portion.

  The airtight nut 71 of the movable valve 70 is installed in the passage port 21 and is exposed to protrude upward from the top of the handle 20 upward. As a result, the inner wall of the passage port 21 limits the range in which the airtight nut 71 is pushed and the strain shifts. Further, the bottom of the connection base 40 is exposed to a position outside the opening 11 at the bottom of the pan lid 10, and a concave tank 44 that is recessed toward the movable valve 70 and communicates with the through hole 43 is installed. The position limiting ring 73 of the movable valve 70 is accommodated and installed in the concave tank 44. A grip portion 23 adjacent to the airtight nut 71 of the movable valve 70 is installed on the outer wall of the handle 20. Thereby, the user can take up the pan lid 10 conveniently and can push and move the airtight nut 71 at the apex of the handle 20.

  At the time of combination, first, the connection base 40 on which the buffer annular piece 60 is fitted and installed is passed through the opening 11 from the bottom to the top of the bottom of the pan lid 10. Thereby, the convex ring 42 of the connection base 40 is made to contact the opening 11 outer edge of the pot lid 10 bottom part. Moreover, the buffer annular piece 60 is sandwiched between the bottom of the pan lid 10 and the convex ring 42. Subsequently, the sleeve 50 is turned downward from the apex of the connection base 40 and is fitted into the outer peripheral wall of the connection base 40. Thereby, the inner thread Yama 51 of the sleeve 50 is tightly fixed on the outer thread Yama 41 of the connection base 40, and the bottom of the sleeve 50 is in close contact with the outer edge of the opening 11 at the top of the pan lid 10. Next, the handle 20 is turned downward from the apex of the connection base 40 and fitted into the outer peripheral wall of the connection base 40. As a result, the inner thread Yama 22 of the handle 20 is tightly fixed on the outer thread Yama 41 of the connection base 40, and the bottom of the handle 20 is in close contact with the apex of the sleeve 50.

In this way, the handle 20 is screwed onto the external thread 41 of the connection base 40 through the internal thread 22 of the passage 21. As a result, the sleeve 50 is in close contact with the outer edge of the opening 11 at the top of the pan lid 10, and the convex ring 42 at the bottom end of the connection base 40 is in close contact with the outer edge of the opening 11 at the bottom of the pan lid 10. Thus, the joint strength of the connection base 40 between the opening 11 and the passage 21 can be improved, and the buffer ring-shaped piece 60 can provide an airtight effect. Moreover, since the sleeve 50 can be tightly pressed between the handle 20 and the pan lid 10 with elasticity, it is possible to prevent the handle 20 from falling off from the connection base 40.
Thereby, the whole structure of the pan lid 10 is further strengthened.

  When the pan lid 10 is put on the pan opening 91 of the pan body 90 and hermetically cooked, the steam pressure inside the pan body 90 rises due to the boiling of the ingredients, and the vapor pressure is movable through the through hole 43. The valve 70 is pushed up. Thus, the vapor pressure is automatically discharged from the through hole 43 and the pressure is relieved. When the heating is stopped, the vapor pressure inside the pot body 90 decreases, and the movable valve 70 recovers the airtight state.

As shown in FIG. 7, when cooking of the food is completed, the user holds the handle 20 and the grip portion 23 at the top of the pan lid 10 with one hand, and with the finger of the same hand, holds the airtight nut 71 at the top of the handle 20. Press horizontally. By doing so, the soft ventilation portion 72 is distorted and inclined, and moved toward the handle 20. Thereby, the through-hole 43 can conduct the air inside and outside the pot body 90 and release the airtight state inside the pot body 90. In this way, the operation process is very simple and convenient, yet smooth and can make cooking of food very easy.
When the airtight nut 71 is pushed laterally and inclined, the airtight nut 71 is stopped by the inner wall of the passage port 21, and the range in which the airtight nut 71 is pushed and distorted by movement is restricted. In this way, it is possible to prevent the movable valve 70 from being detached from the through hole 43 due to excessive inclination of the airtight nut 71.

  The external force when picking up the handle 20 is dispersed on the outer peripheral wall of the connection base 40 on the average. Thereby, an external force acts on the inner wall of the opening 11 of the pan lid 10 through the connection base 40 outer peripheral wall on average. Thus, an annular contact surface is formed between the outer peripheral wall of the connection base 40 and the inner wall of the pot lid 10 opening 11 to improve the rigidity and durability of the structure, and external force is applied to the single contact point of the pot lid. Concentrate and avoid the problems of curving deformation and rupture of the pan lid.

  The foregoing is only a description of the preferred embodiment of the present invention, and is not intended to limit the present invention, and any other modifications or substitutions of equivalent effects that may be completed without departing from the spirit of the present invention. Are also within the scope of the claims of the present invention.
